SYNOPSIS

       type: NSR layout

DESCRIPTION

       The  NetWorker  server filesystem has a directory called /nsr that con-
       tains log files, on-line indexes, and configuration information.   This
       directory  can  be created in any filesystem with /nsr set up as a sym-
       bolic link to the actual directory (this is determined at  installation
       time).  The format of this directory is as follows:

       /nsr/logs
              Contains  server  logging messages.  The files in this directory
              are in ASCII format.

       /nsr/res
              Contains the configuration files for various components  of  the
              NetWorker  server.  For example, the server stores configuration
              files in /nsr/res/nsrdb.

       /nsr/mm
              Contains the media index.  Information  about  the  contents  of
              this  index  file can be printed with the nsrls(1) command.  See
              the nsrmm(1) and mminfo(1) manual  pages  on  how  to  view  and
              manipulate the media index information.

       /nsr/index
              This  directory  contains  subdirectories with names that corre-
              spond to the NetWorker clients  that  have  saved  files.   Each
              index  directory  contains files that allow the NetWorker server
              to provide an on-line database of the client's saved files.  The
              most  important  element is the db6 directory which contains the
              NetWorker save records and access indexes to those records.  The
              disk  space utilized by the index grows with the number of files
              saved by the NetWorker service.  Administrators should  plan  to
              use  about  200  bytes  per  saved  file instance placed in this
              index.  There are no practical limits on the maximum size of  an
              online  index, except that it must reside entirely within a sin-
              gle file system.

              The format of the db6 directory is subject  to  change,  and  is
              accessible  only through an RPC interface to nsrindexd(1).  How-
              ever, the nsrls(1) command can be used  to  obtain  some  useful
              statistics  from  this  directory.  The nsrck(1) command is used
              for checking and rebuilding index files as  well  as  recovering
              index files from backup media.

              The  data  in the files in the db6 directory are stored in plat-
              form-independent order, so these files may be migrated from  one
              NetWorker server to another.  Moving the media database from one
              NetWorker server to another of unlike architecture is  not  cur-
              rently supported.
                     representation of the time.

              <savetime>.k0
                     These  files  contain the keys on the <savetime>.rec file
                     based on file name.

              <savetime>.k1
                     These files contain the keys on the  <savetime>.rec  file
                     based  on  inode.   These may be zero length files if the
                     client file index is for a windows client.

              <savetime>.sip
                     This is a save-in-process file and  only  exists  when  a
                     save  has been started and is not yet complete.  Once the
                     save is complete, this file is renamed to <savetime>.rec.

              v6hdr  This  file  contains  a summary of all the <savetime>.rec
                     files that exist in a client's db6 directory.

              v6journal
                     This file contains updates to the  v6hdr  file  that  are
                     waiting  to  be  merged  into  the v6hdr file.  Any index
                     operation includes the entries here as well as  the  ones
                     in the v6hdr.

              v6ck.lck
                     This  file  is a lock that nsrck uses to ensure that only
                     one nsrck operates on a client's index at any given time.

              v6hdr.lck
                     This  file  locks the v6hdr for reading and the v6journal
                     for reading and writing.

              v6tmp.ptr
                     This file refers to the working directory in  which  con-
                     version and recovery will take place.

              tmprecov
                     This  is  a  working  directory  in  which conversion and
                     recovery take place.

              recovered
                     This directory contains intermediate results of an  index
                     that  has  been converted or recovered.  The results here
                     are complete and will be integrated into the  file  index
                     when nsrck is run against this client file index.

       /nsr/cores
              Contains  directories  that  correspond  to the NetWorker server
              daemons and certain executables.   Each  directory  may  contain
              core  files  from  NetWorker  server daemons or executables that
              have abnormally terminated.

       /nsr/drivers
              This directory may contain any device drivers for use with  Net-
              Worker.

       See pkgadd(1M)  for  details  on  alternate  executable  locations  for
       Solaris 2.x.

       When executables for more than one architecture are installed, the non-
       native  architectures   are   by   default   put   in   the   directory
       /export/exec/arch/etc,  where arch refers to a given architecture name.
       A different location to install non-native executables can be chosen at
       installation time.
